I freely admit that it's a stretch, but I'd rather scan/photograph a public key than try and copy it by hand (which base32 is also better at). And I won't put a USB device of unknown provenance into a device I use. So sometimes pictures and or printouts are a good way of sharing data.
It also occurs to me that OCR implies a computer, but it could just as legitimately mean a human reading text
- bastawhiz 10y agoIf you're sharing this stuff optically, you'd almost certainly be better off with something like a big QR code. QR can be scanned at angles, has built-in error correction, and (depending on the font you're comparing it against) can probably pack in more bytes. OCR feels more like a hack than anything; you're using a human-readable format with an error-prone medium to communicate non-human-friendly data between two machines!
- zo1 10y agoQR codes are actually quite versatile. I've had success taking plenty of raw text, zipping it and storing the resulting bytes in a QR code.
